Prognostic Value of Cerebrospinal Fluid and Serum Neurofilament Light Chain in Amyotrophic Lateral Sclerosis: A Correlation Study.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe diagnostic and prognostic values of serum neurofilament light chain (sNfL), in comparison to cerebrospinal fluid (CSF) neurofilament light chain (cNfL), and other clinical parameters in amyotrophic lateral sclerosis (ALS) at the time of diagnosis remain elusive.
methodsWe examine paired serum and CSF samples from 80 ALS patients and 21 control subjects, all obtained at the time of diagnosis. Additional serum samples were collected from 51 other ALS patients. NfL concentrations were quantified using the single molecule array (Simoa) technique.
resultsOur findings demonstrate a robust correlation between NfL levels in matched CSF and serum samples. Notably, both sNfL (p < 0.0001) and cNfL (p < 0.0001) exhibited significantly elevated levels in ALS patients compared to controls. Furthermore, baseline sNfL concentrations, as well as cNfL levels, emerged as predictive indicators of subsequent disease progression rate (sNfL: p < 0.0001, cNfL: p = 0.0005) and overall survival (sNfL: p = 0.0073, cNfL: p = 0.0044). Employing a Cox regression model, we identified baseline sNfL level (HR = 1.01, p = 0.013), and diagnostic delay (HR = 0.94, p = 0.003) as independent prognostic factors for mortality. Furthermore, we constructed a nomogram model that incorporates both sNfL and pertinent clinical variables, which substantially enhances the accuracy of predicting disease outcomes (Concordance Index, 0.808).
conclusionOur study underscores the robust correlation between sNfL and cNfL in ALS patients and establishes baseline sNfL as a potent and independent prognostic marker for mortality.
